Water Conservation Plan- Approved by Cwcb - Arvada

(3) Expand the gross

(3) Expand the gross square footage of the floor area of the car wash installation building by more than 50 percent of the square footage of the car wash installation building as it exists on June 1, 2003. (d) All self-service car wash installations shall be exempt from the provisions of this article. (Code 1981, § 33-59; Ord. No. 3761, § 1, 2-3-2003) Sec. 102-109. Irrigation water to landscaped common area. (a) The annual allocation of water for irrigation of the total landscaped common area is included in the annual allocation of water acquired when the tap fee is purchased for the residential or nonresidential type of property as set forth in sections 102-34, 102-161(3) and 102-163(3). The city will permit installation of up to three service connections to the city water main for the common area irrigation system by the property owner or responsible caretaker association upon payment of connection costs, tapping and inspection fees as set forth in sections 102-44 and 102-164(a)(1) and (2) or section 102- 166(a)(1) and (2). Each landscaped common area irrigation service connection will be assigned a service address and billing account in the name of the property owner or responsible caretaker association. The department of utilities prior to issuance of building permits must approve the landscape and irrigation plans. (b) All determinations concerning qualification as landscaped common area, non-water conserving open space, water conserving open space or nonirrigated open space, and all determinations as to the size and type of irrigation tap required, shall be at the sole discretion of the director of utilities or his duly authorized representative, consistent with the provisions of this article I. Any such determination involving area demarcations or calculations, or volumetric calculations, shall be made available to the user for inspection, upon request. (Code 1981, § 33-61; Ord. No. 3202, § 4, 8-7-1995; Ord. No. 3262, § 7, 4-15- 1996) Sec. 102-110. Irrigation water demand for open space. (a) For nonwater conserving open space, the annual volumetric water demand shall be calculated at 18 gallons per square foot per year for the purpose of establishing the size and cost of the irrigation tap to be purchased in accordance with sections 102-34, 102-164(b), and 102-166(b). (b) For water conserving open space, the annual "volumetric" water requirement for irrigation shall be calculated at nine gallons per square foot per year for the purpose of establishing the size and cost of the irrigation tap in accordance with sections 102-34, 102-164(b), and 102-166(b). 34

(c) For open space that has no installed irrigation system and will not be irrigated, no water demand will be assigned. (d) All determinations concerning qualification as landscaped common area, non-water conserving open space, water conserving open space or nonirrigated open space, and all determinations as to the size and type of irrigation tap required, shall be at the sole discretion of the director of utilities or his duly authorized representative, consistent with the provisions of this article I. Any such determination involving area demarcations or calculations, or volumetric calculations, shall be made available to the user for inspection, upon request. (Code 1981, § 33-62; Ord. No. 3262, § 8, 4-15-1996) Rebates and Incentives Between 1990 and 1995 the City of Arvada provided rebates to customers who replaced non-conserving toilets with ULV toilets using 1.6 gallons or less water per flush. Over the five year period, 3,410 ULV’s were installed. The project cost the City at total of $265,500, and saved 80.4 AF of water. In 2002 and 2003, the City implemented five rebate programs at a cost of nearly $400,000. Table 11: Previous Rebate Programs Rebate Name Number of Participants Cost Deep Root 648 14% $6,477 2% Soaker Hose 854 19% $8,317 2% Toilet 1,583 35% $173,177 46% Clothes Washer 716 16% $89,500 24% Landscape 700 16% $99,952 26% Total 4,501 100% $377,423 100% Rebate programs are quite costly in comparison to other water-saving measures. Incentives for buying eco-friendly products can lose their effectiveness as those products become widely available and prices drop. Many municipalities across the country are dropping their rebate programs in favor of more cost-effective measures, such as the Garden-in-a-Box and water-use audits the City will be implementing in 2013. The City does offer reduced tap fees as an incentive to encourage conservation. As explained in the Landscape Efficiency section of the Plan, 35
